Jon Jones 'B' sample confirms USADA violation, substance(s) remain unknown

Tough break for Jon Jones.

After failing an out-of-competition drug test taken by United States Anti-Doping Agency (USADA) back on June 16, it now seems as if the "B" sample to that test also came back positive, per a report by Jay Glazer on FOX Sports 1's UFC 200 weigh in preview show earlier today.

Jones was recently pulled from UFC 200's main card for failing said test and was subsequently replaced by Anderson Silva, who will now step in on two days notice and fight Daniel Cormier in a non-title bout.

Unfortunately for Jones, possessing two failed samples isn't going to do him any good in avoiding the standard two-year suspension that comes with a USADA violation. And even though Jones denied knowingly taking any banned substances in a press conference earlier this week, there's not much he can do now to alleviate the crushing publicity that comes with another career misstep.

At just 28 years of age, the former Ultimate Fighting Championship (UFC) Light Heavyweight king could eventually get back into the saddle, but he's facing the longest and most strenuous road yet. And that's saying something considering Jones' personal struggles outside of mixed martial arts (MMA).
